What is textFormat?
It isn't a StringBuilder is it?
textFormat.append(subText);

for (Integer posLetter: positions){

with fullText = 5M and textFormat that's even bigger it crashes.
An friend tried with a 15M file using Lingo language and it worked without
problems and I bet .NET would have no problem either but I'll know tomorrow.
Sorry to hear that.
Would you please show some source code relative to the problem?
Well, 5000 loops of substring with a big string is terrible.

It wasn't there but I added it and whatever I used -Xmx or -XX, it didn't
work. I wrote 100m for the -XX...
I also checked again where I could optimized and where I could find memory
leakage. Reducing the number of string meant using StringBuilder's
insertthe slowness of that command makes it not an option. I couldn't
find any memory leakage.
Where the program systematicaly crash is a loop where I do a substring of
the big string everytime(about 5000 loops).I then fill a StringBuilder
which
will eventualy be bigger than the main string. That's the fastest way I
can
do what need to be done and it needs to be fast.
I'm starting to loose faith in Java...I'll ask a friend that

Re: i18n Issue for Chinese Locale.
Everything looks good. UTF-8 is fine for Chinese. You are getting 9
bytes as a result, which is what you should get for UTF-8 encoding,
which is good. But it seems the browser isn't reading it as UTF-8 and
just displaying the bytes instead under the default ISO encoding.
Try adding this
If that doesn't work, can you post the html that is generated.

Re: Submit form with and
I like the tag due to the ability to have markup inside the button, except that it is no use because IE doesn't follow the standard. You can use with fancy html in here like bold for example which makes nice buttons with mark-up and stuff. You can have several of these type="submit" buttons in a form. What you would expect is for only the button that is clicked to submit the form and send it's value, but IE sends the name/value pair of any button element in the form, so you can't tell which button was clicked. Works in FireFox though. Laurie Harper wrote: No, *I* confused us both I think... I was talking about the HTML element, not the element... Seems odd they wouldn't be equivalent, but still!

Re: a little bit OT: Calendar misbehaviour
If timezone if the problem, then use SimpleDateFormat.setTimeZone() and

eliminate the timezone correction and give you the right number.

The point is, that getTimeInMillis() is returning 0 if timeString contains
only minutes (like "00:20") while cal.getTime().toString returns properly
"Thu Jan 01 00:10:00 CET 1970".
Why is it so? How can I initialize that Timestamp with such a string if
this

I know what is the cause of this problem but still don't know how to work
around this... :-(
The problem is that in Poland we have GMT+01 time zone. Therefore default
time zone here is set to GMT +01. And time "Thu Jan 01 00:10:00 CET 1970" is
not translatable to milliseconds because getTimeInMillis() returns time in
UCT and it would be 50 minutes before Epoch...
Can anybody suggest any way of parsing time string to Timestamp? Is using
separate fields for hours and minutes the only solution available?

Re: [IMPORTANT] tomcat 5.0.19+ is broken / not useable with struts / your voice needed

I wonder if the new java.util.concurrent classes could be used instead
of simple HashMap?
http://java.sun.com/j2se/1.5.0/docs/api/java/util/concurrent/ConcurrentHashMap.html
but that would mean total dependence on j2se 1.5 and that would be a

http://www.mathcs.emory.edu/dcl/util/backport-util-concurrent/

to whom it may concern
There is a serious bug in tomcat 5. To make it short, if you write to or
read from session (taglibs included) and have a chance that there is more
than one request from same user currently proceeded on the server (and it
can be just a web-page refresh, our beloved F5 key) you are f**ked.
What happens is that the HashMap where the session attributes are stored got
corrupted, and the entry.next in the HashMap points to itself (or start of
the list). Next request to the session.getAttribute results in an endless
loop, and your server has 100% cpu load.
You can read full bug description at:
http://issues.apache.org/bugzilla/show_bug.cgi?id=36541
What does it mean for us, struts-users?
If we use the session scope:
1. Struts-taglibs aren't thread-safe.
2. Application that are working under tomcat 4.1 or resin, or probably any
other servlet container will not work under tomcat 5 (or are not reliable).
3. We must forbid users to have multiple browsers open.
4. We can't handle multiple frames or concurrent requests from same user /
session.
5. ... many other examples available.
affected versions:
5.0.19+
5.5.x
If you ever had actions hanging around in
session.getAttribute()/HashMap.get() for hours and don't know why -> it's
your bug.
What can you do:
Please, click the bug link

P.S. One more thing, could struts-developers team supply a patch for tomcat

Re: Upload: strange characters in german filename
Looks like the filename is being sent as utf-8, but being read as Latin1
(can't remember the iso number).
Struts uses Commons FileUpload to handle the file uploads. By default
it uses org.apache.struts.upload.CommonsMultipartRequestHandler
Now Commons FileUpload has a method called setHeaderEncoding (-
http://jakarta.apache.org/commons/fileupload/apidocs/org/apache/commons/fileupload/FileUploadBase.html#setHeaderEncoding(java.lang.String)
If you can call FileUpload.setHeaderEncoding("utf-8") before the headers
are read that should fix the problem. One way to do that is override
the default handler with your own one in struts-config.xml eg
Then to modify org.apache.struts.upload.CommonsMultipartRequestHandler
by creating our my.own.MultiPartClassHandler class.
We need to modify the handleRequest() method like so:
// Create and configure a DIskFileUpload instance.
DiskFileUpload upload = new DiskFileUpload();
upload.setHeaderEncoding("UTF-8");
// Set the maximum size before a FileUploadException will be thrown.
upload.setSizeMax((int) getSizeMax(ac));
...

Re: Dealing with nulls
Whether you store nulls in your database is really a design decision you should be making based on your requirements. Taking the date example for a moment. If the date is required then it shouldn't be able to be null in the database and a record shouldn't be created until you have a valid date. However you might have optional dates. In these cases you may use null to show that the date has not been set yet. Setting the date to some funny value may mean you have to jump through hoops to filter out these dates from queries in other parts of the application. I'll see if I can whip up an example... How about a date that is used to record when some process has completed. It will be called endDate. It can be null in the database because the process has not finished yet. Now a struts action is called to update the process. My struts action talks to my application objects which do the database retrieval and populate an object representing the process. The there will be some methods such as Date getEndDate() and setEndDate(Date date) so I can rad/write to the field. Next, I need to transfer this to my form object. Struts won't deal with Date objects on a web page, it needs to deal in strings. So we will have String getEndDate() and setEndDate(String date) on the form object. These will be used by our form fields for display and populating when the form is submitted. So the tricky thing is how to convert my date into a string and the reverse when we want to read the date off the submitted form. The easiest may be to tack some extra methods onto the form object eg setEndDateAsDate(Date date). This takes the date object, which may be null, and generates a human readable version using SimpleDateFormat for example, or storing an empty string in the form object. Same goes for retrieving the endDate from the form. We might add Date getEndDateAsDate(). This method will check if the string is empty, if so it returns null. If the string isn't a valid date it returns null. If the string can be converted into a valid date using SimpleDateFormat, the date object is returned. You might also like to add an boolean isValidEndDate() method. If the string returned is not empty, the string is checked for a valid date, if it fails the user can be asked to reenter the date. This means your application doesn't have to change deal with the nulls/empty strings/incorrect dates are entered. Murray Collingwood wrote: Hi all Just like to say I really appreciate the help you guys provide us newbies. I'm looking forward to the day I will be able to help others... What convention do people normally use for dealing with NULL values from an SQL database? I can retrieve them okay. I can store them in my form class okay. But when Struts tries to display them on a form I get an exception. 1. Do you test them at the SQL retrieve and set a displayable value? eg change a null string to an empty string, change a null date to 00/00/ 2. Do you handle them in the form class with different getters and setters? eg a different property name for displaying them on the form 3. Do you handle them on the form somehow? (not sure how you would do this) 4. Or do you simply set your database so that the fields can't be null and give them defaults, ie strings always default as empty strings? Currently I'm tyring to use method 2, coding different property names in the jsp and using the getter and setter methods to transfer the null value to something that can be edited.

Re: [OT] MessageFormat and curly brackets
From the java docs for MessageFormat:
Within a String, "''" represents a single quote. A QuotedString can
contain arbitrary characters except single quotes; the surrounding
single quotes are removed. An UnquotedString can contain arbitrary
characters except single quotes and left curly brackets. Thus, a string
that should result in the formatted message "'{0}'" can be written as
"'''{'0}''" or "'''{0}'''".
So at a guess, something like:

Re: [OT] Re: ajax proj
Just a quick note/question about Craig's code below:
This line
${category.label}
will output the value with not xml filtering, so some values will cause
incorrect xml to be generated.
You should use tag to filter the <,>,',", and & characters to
output <, >, ', ", and &
and the same for the element

Indeed it is. If you actually need to create XML in a response to an
XmlHttpRequest call from an Ajax client side gadget :-), here's an
approach using a JSP 2.0 page (in xml syntax) that uses JSTL to
iterate over a result set, and JSP expressions to pull out the data
(copied from the Shale Use Cases example app):
http://java.sun.com/jsp/jstl/core";
xmlns:jsp="http://java.sun.com/JSP/Page";>
${category.label}
${category.value}
The business logic that looks up the label/value pairs for the
response doesn't have a clue how it will actually be rendered, and
setting up a JSP page is much easier to author than building an XML
DOM in Java code.

Re: Place message in jsp from action?

try something like this:

messages.add(ActionMessages.GLOBAL_MESSAGE, new
ActionMessage("global.error.database.problem"));
saveMessages(request, messages);
then in the jsp
ActionErrors are being deprecated (from what i recall) and replaced
with ActionMessages.

// Get access to the message resources for this application
// There's not an easy way to access the resources from an ActionForm
MessageResources resources =
(MessageResources)request.getAttribute( Action.MESSAGES_KEY );
// Check and see if the access number is missing
ActionError newError = new ActionError("global.error.database.problem");
errors.add(ActionErrors.GLOBAL_ERROR, newError);
And then tried to pull the error out (just like an form error), but the error never shows?
I figured I am missing something, or possibly there is a better way to handle this?

hmm, having said that, it might be weird if the default behaviour was
to filter.
eg comparing

would have the second one filtered twice.
It might be possible to only filter when not inside a tag. But that
might then look inconsistant. bah.

The security part of this was mentioned on the list sometime

any HTML-sensitive characters, but the straight EL language
does not. So, let's say that your variable 'EL' that you
were using is a String:
" would print:
<script language="_javascript_"
href="" and the user
would just see the characters -- no harm done.
${EL} would just print the String, and whatever script is
included in 'nastybad.js' would be executed on the end-user's machine.
If you are confident that the contents of your EL variable
couldn't possibly have any harmful HTML in them, go ahead and
use ${EL}.

Re: Hiding pages under WEB-INF
I hide JSPs under WEB-INF, but I leave my images, .css and .js files outside so they can be served by the web server. I use forwards in struts to handle url rewriting, instead of linking directly to the css from a .jsp eg Unless there is a reason (eg restricted access etc) I wouldn't use an action to serve these types of files. The action would have to make sure you can't traverse directories, set content mime-types etc. I imagine it would iterfere with a browsers if-modified requests causing a browser to continually download images/css/js pages every request instead of caching them. Frank W. Zammetti wrote: Jarnot Voytek Contr AU/SC wrote: > Right, js, css, and image files don't belong under web-inf. I know someone who will disagree vigorously (where are you D.J.?!?) :) Seriously though, many people DO use this technique, and you can in fact put everything under it, even the js, css, img, etc. content... For the OP... as you found out, you can't just link to anything under WEB-INF, as is the intention of that folder's protection. What you will need to do is build yourself an Action that returns the requested item, then point everything at that Action.

But reading the specs it does say the same thing you say above eg you

I think I would prefer to have escaping on for almost all of my ${}

You can extend the main.layout and override the title for the

If you have different pages and want different results by overriding,
that is a different issue altogether. Overriding does not solve the

them but different than your approach too. I make the title tag's

itself to Tiles, although maybe I should switch to what Lesaint is
doing. How come the French seem to be so adept at GUIs? Maybe there
is just a deep sense of style in the French psyche?
There are several levels to the i18n problem. The simplest is just
picking the correct string to output on a particular page such as a
title.
This isn't necessarilly tying yourself to tiles, you could specify the
title key in your action or each individual .jsp page. It certainly
makes it easier to maintain. Just match up keys in tiles to keys in
your application.properties files and .jsp files.
Easiest way to demonstrate is a few examples:
application_en_US.properties: login.title=Hello
application_en_NZ.properties: login.title=Hi Mate
application_en.properties: login.title=Hi
In Tiles, we use the examples above because they are fine:
In your layout.jsp page we use the following:
That name="title" will look up the applications.properties file and
pick the string depending on your locale. So we should see either
"Hello","Hi Mate", or "Hi". This can also be done in JSTL (may have to
set the resource bundle to be the same one struts uses)
Now you say your titles need to be dynamic - it really depends on what
information changes in this title. This is the next harder step in
i18n, but it isn't too difficult to do:
application_en_US.properties: login.title=Hello {0} {1}
application_en_NZ.properties: login.title={1}, Hi Mate
application_en.properties: login.title=Hi {0} {1}
Above we have put in the {0} substitution points where the information
will appear. If we want {1} to be their title eg Mr Mrs and {0} to be
a person's name.
or in JSTL (assuming we have a user object with user's name and title)
We should end up with output
en_US: Hello Mr Smith
en_NZ: Smith, Hi Mate
en: Hi Mr Smith
It get's trickier when part of the text should change based on numbers
eg 0 files, 1 file, 2 files as {0} file wouldn't work
But the above should deal with most of the common uses

Re: Attributes Initialization
1. From what I see here you redirect from index.jsp to submit.do.
2. The submit.do action is defined to have validation.
3.*My guess* is that validation fails, and you are returned to your
input page (input="submit.jsp") and the execute method is *not* executed
4. You submit a form from submit.jsp to submit.do, validation succeeds,
execute() executes normally
To fix this you would need a new action which has validation turned off
(if i remember correctly, unless there is some other way to do it)
eg
and
index.jsp should change to
<%@ taglib uri="/tags/struts-logic" prefix="logic" %>

Wendy,
I know that the method is not executed, because I put a 'print' statement as the first line in the method. The 'print' statement does not appear initially in Tomcat. It does appear only after submitting the form.
I also added a no-arg constructor for the action class. It is used only after a form has been submitted.

index.jsp redirect to 'submit', which is defined as a global forward as
'submit.do'.
If you're redirecting to submit.do, given the configuration you've posted,
SubmitAction should be executing.
What do you have in execute()? Why do you think it _isn't_ executing? The
thing is... typically, the execute method does whatever it needs to do, then
calls mapping.getInputForward(). If execute isn't executing, how are you
ever getting to your form?
Here's a guess: in SubmitAction.execute(), you're putting things in the
request, then *redirecting* to your form. If so, the browser will make a
new request for the redirect, and the things you put in the original one
will be lost.
I'd have to see SubmitAction.java and whether there is anything interesting
in the log files in order to offer any further guesses.
I can define it as 'submit.jsp', but there is no difference in behavior.
No, that's definitely not going to fix it. Everything needs to go through
an action, which you seem to be doing.

If you can't change the database to Unicode/UTF-8 encoding then you
would have to convert strings going into and coming out of the
database. This would be the best option for reading/writing the
database. Everything else takes a lot of extra work. You maybe able to
dump the database and recreate a new one as Unicode/UTF-8 and then
reload the data. There may be functions in Oracle 8i has any functions
that might do this for you, or perform string conversions.
Another option which would be full of difficulty would be converting the

inserting into the database, and then converting from UTF-7 to Unicode

Re: Help! Problem with "isTokenValid"
You need 2 actions. The first saves a token, then displays the form.
The 2nd action is called when the form is submitted, and the code below
looks ok.
I assume you either don't have an action to populate the form (eg the
user opens the .jsp form directly), or the action does not save the token.
When your action to process the form checks for a valid token, the token
doesn't exist, so it is invalid and you return your error message.

Re: Checkboxes with display tag
I think you need to be using multibox for this to work. I just did
something similar recently and this is how I did it:
I am using JSP2.0+JSTL+EL. Using id="row" in the display:table gives me
a handle to each object in the list so I can get the id for each row.
Then I use ${row.id} to use as the value for the checkbox. To do the
same without JSTL I assume you would need to use:
(but I haven't tested that)
This gets submitted to an ActionForm with these properties:
public class MyActionForm extends ActionForm {
private String[] deleteList=new String[0];
public String[] getDeleteList() {
return deleteId;
}
public void setDeleteList(String[] fileId) {
this.deleteId = fileId;
}
public void reset(ActionMapping mapping, HttpServletRequest request) {
deleteList=new String[0];
}
...
}
This gives me an array of all the id's corresponding to the ticked
checkboxes, which I might update in a database.
Hope that gives you some clues - but probably more questions :)

Re: OT: jstl equivalent of logic:present
I couldn't find a way in JSTL/EL using the standard tags. So it looks like we need a tag with that ability. In that case it probably doesn't matter if you use the logic tag or the other suggestion of the request tag. I see that the logic tag allows you to check for more than 1 role eg whereas the request tag does not, so there may be a benefit with still using the logic tag.

Re: Internationalizing a Struts project
Yes, I use the setCharacterEncoding(...) in a filter on Tomcat 4.1.28 to
handle UTF-8 encoded pages (mainly for communicating in Japanese, which
should be a good a test as any for UTF-8). I set the encoding to UTF-8
on each page as Craig suggested so the browser knows the encoding, and
use a Filter to force the requests to be UTF-8 encoded before struts
reads the parameters.
I don't know about other servlet containers. Perhaps those other
containers are not complying to the specification.
There used to be a good resource "*Struts i18n*

This issue is more related to the way JSP works than Struts, but
here's a summary.
The most important consideration for national characters is the
character encoding that will be used to send the response
back to the
browser. Unless you ask for something different
explicitly, JSP pages
are always sent back in ISO-8859-1 (basically 7-bit ASCII),
which will
create problems with characters outside the 7-bit range.
To ask for the content encoding to be set differently, you use the
page directive at the top of your JSP pages, for example, to select
UTF-8:
<%@ page contentType="text/html;charset=UTF-8" %>
If all of your national characters are produced by custom
tags (such
as or in the case of Struts),
this should be
all you need. If you also want to use literal characters in the
template text of your JSP page, you have to go one step further --
actually store the source code of your JSP page in an appropriate
encoding, and tell the JSP compiler what that encoding is. The

Re: Internationalizing a Struts project
You should only need to do the following:
request.setCharacterEncoding("UTF-8")
before the form is populated. I think you can do this by overriding the
RequestProcessor. I use a filter to do this instead.

Hi, Craig.
You hit the bull's eye. No I claim this not only to be a JSP/Servlet problem.
The way you describe will cause the browser to encode all form data with UTF-8.
Unfortunately the servlet container (Tomcat in my case) does not know about this.
To obtain the correct parameter values, someone has to call (beware of Nullpointers

Re: Can I detect file size without uploading?
struts Dude wrote: Cool! I was told 'detect file size without uploading' is impossible. But you said 'might work' above, have you or anyone actually tried this?? OK, I am lazy to try this myself, but hey programmers are lazy. Well, I'm lazy too :) I just came up with the idea. Whether it works is up to the people interested in it to test the idea. From a glance at the servlet spec, this sort of thing might depend on the implementation. The servlet spec doesn't say the request object must be completely filled with the entire request when the servlet is given the object. So I assume it creates a request object, reads the header and populates it and provides an input stream for the object to use later. If you access parameters then it has to read in the stream, and then you must wait for the entire request to be sent. If you just check the headers then I assume the entire request isn't read and you can return a response before the entire request is sent by the browser. But some containers might read the entire request (though I would doubt it as that would load it all into memory). I don't need this functionality, so I won't be testing it. If you do test it, can you post back to the mailing list with your experience so others can see he result. -- Jason Lea - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Can I detect file size without uploading?
You could shortcut the process using a filter.
You create a filter that checks the content length of a request, if it
is above the threshold intead of passing the request through the normal
path, you forward the request onto another action that writes out an
error message without consuming the whole request.
Something like this might work:
public class FileUploadSizeCheck implements Filter {
int maxLength = 100;
public void destroy() {
}
public void doFilter(ServletRequest req, ServletResponse res,
FilterChain chain) throws ServletException {
if (req.getContentLength() > maxLength) {
request.getRequestDispatcher("/some/new/destination").forward(req, res);
} else {
chain.doFilter(new
UploadRequestCounter((HttpServletRequest)req),res);
}
}
public void init(FilterConfig arg0) throws ServletException {
}
}

gus a écrit :
I'm using a Struts ActionForm to upload a file using a "multipart/enc"
POST. The files being uploaded are sometimes rather large and we
wish to restrict them to ... 5 to 10 megs.
Currently we are doing this:
--- inside the effected tile
...
--- inside execute() for Action processUploadAction
...
final FormFile attachment= uploadForm.getAttachment();
int attachSize = attachment.getFileSize();
if (attachSize > MAXATTACHSIZE){
actionErrors.add("error.attach.toobig");
return request.findForward("fail");
}
...
Now the issue with this occurs when a user uploads a large file. Let's say
they are uploading a 90 megabyte file. This takes 30 minutes. Our
session timeout is set to 25 minutes. The user is logged out, we
get errors, and the operation fails miserably.
The ideal situation would allow for me to detect the file upload size
before the user uploads, and before they time out.
The following issues prevent me from being able to exhibit the ideal
situation:
1.) By the time I have reached the action the post has already
taken place.
2.) Even in the ActionForm.validate method, I can't see the
size of the file before it has been uploaded.
3.) Using the controller setting, "max-file-size" seems the viable means
to handle this, but unfortunately, this seems to still not restrict the
established rule before the file has been completely uploaded.
Additionally,
it is not clear to me as to what the controller does when this max-file-size
threshold is reached -- how do I intelligently produce an error before
my action is touched?
Ideally, what should be happening is we should be able to detect
how large the file being uploaded is before the post even occurs.
For example, we could look at "request.getContentLength()" and
do something smart based on that.
Essentially, it looks as though I may have to create a custom request
processor for my purposes because the existing functionality
afforded by the Controller is inadequate for our designs. I wish to
make sure that this is the case. If this is the case I take it I should
start with writing an extended RequestProcessor class that overrides
the processPreprocess method and then performs operations on the
actual parameters/request object to make sure the content length
is short enough.
Any thoughts and help is appreciated.

Re: JSTL problem

How JSTL and Struts communicate each other?
Could anybody please explain this *mysterious* thing detailly?
I really want to know the black box behind JSP using JSTL
and Struts taglibs , but the servlet code compiled from
JSP is too hard to explore.
The main points are that Struts puts form beans into either the session
or request scope depending on what you configure struts to do.
The JSTL looks through the different scopes in order for the bean name.
So the way to tie JSTL and Struts together is to know what the name of
the bean that Struts has put into the scope.
From struts-config.xml you might have:
When this is used with an action it is put into the session/request
scope under the name 'myFormBean'
So to use it in JSTL you can just use ${myFormBean.abc} to access the
myFormBean.getAbc() property.
Regards.

Yes, the user principal lives in the session. When the session expires
or is invalidated you are logged out. This makes logout buttons easy
too, just do session.invalidate() and the user can log in as a new user.
You can manually set the session timeout on the session object (I
believe), or in your web.xml you can use
30
with the number of minutes you want the session to live.
Also found out that I don't need a separate login
form for each different user. 1 login form for all
user is allowed. duuhh me.
yep
I don't quiet see the need to define
restricted URL in securityfilter-config.xml as
Admin Page
/admin/*
admin
if I simply add roles attribute in action mapping of struts-config.xml.
All my restricted action mapping has user roles attribute rather than
using path attribute e.g. path="admin/bla". I hope that is not bad practice.
Using the security constraint means you can also protect static html
pages too. If you have /admin/abc.html or /admin/abc.jpg these would
need the user to be logged in as admin to view them. What ever is
easiest for you. It can be nice to know that any thing in /admin/*
needs a role of admin to access it, where as if you forget to add
role="admin" to an action you might not notice.
Also, it looks there is no way to use client/server side struts validation
to
convey error message on login form. E.g. password is incorrect.
Yes, sort of. If your securityfilter-config.xml does this:
/LoginError.do
Then the LoginError action can put the error messages into the
ActionErrors like any action does, then display the login.jsp.
login.jsp can display the error messages as you would normally. You
won't know whether the password or username were incorrect. So a
generic try again message should be ok.

Ok, using filter (as u said) after SecurityFilter wud solve this simply
but
I like to stick with pure Struts approach if possible.
Struts is sitll happy to use filters - it was created before filters
existed. It really comes down to what you are happy with and what level
of container you want your app to work with.

Using action to put bean in Session after SecurityFilter, how is that
possible when after authentication by SecurityFilter, u taken right
back to /user/abc.do where u 1st request it and doesn't pass
through to action attribute as specified in action-mapping of
struts-config.xml?
you create a base class like
public class BaseAction extends Action {
public ActionForward execute(...){
... do stuff that every action needs, eg checking for/putting
user bean in session
}
}
Then your other actions do something like this
public class MyFirstAction extends BaseAction {
public ActionForward execute(...){
super.execute(...);
... do whatever your action does
}
}
This way, the piece of code that you want every action to execute is in
one place.
I have tried to use action, after authentication, I am indeed taken
back to the page /admin/logon.do or /user/logon.do and got
error message in browser:
HTTP Status 400 - Invalid path /admin/Logon was requested
message Invalid path /admin/Logon was requested
description The request sent by the client was syntactically incorrect
(Invalid path /admin/Logon was requested).
Is that the url you tried to access or was it something in the
securityfilter-config.xml? Whatever it is, it's missing the .do at the
end eg /admin/Logon.do.
But if it is in the securityfilter-config.xml as a login form then it is
wrong, as only administrators can access /admin/*

Re: JSTL Tag problem!!
Sounds like you are using Tomcat 5, which allows EL expressions anywhere.
eg instead of you can use
${title}
It also means you don't need to use the html-el tags, just use the
normal

Subject: Re: SecurityFilter Question?
As for populating a User bean into a session once they are
authenticated I have done this in the past with a filter. I place
it after the security filter in the chain of filters. It checks if the
user is logged in, if they are and there is no session bean, the filter
creates+populates the bean and stores it in the session ready for any
action that needs to use it.
Can't u do this using an Action? Say, accessing /admin/LogAction.do
invokes SecurityFilter, after authentication by SecurityFilter is passed,
go directly to LogAction as below
The problem comes if the user bookmarks a url like /user/abc.do, starts
up their browser and goes directly to the protected URL. The security
filter will take them to the login form, they submit username/password
and seucirty filter authenticates them. Once they are authenticated
they are redirected back to /users/abc.do - they don't pass through
LogAction at all. So I normally have a filter that makes sure the bean
is in session from where ever they are called.
You don't have to use a filter though, you could make a base action that
does puts the bean into session and have all your actions sub-class that
one.
validate="false">
name="success"
path="/pages/Welcome.jsp"/>
Within LogAction class, construct User bean from logonForm and
add it to session. Is that possible or is the request parameters from
logonForm lost?
Can u be more specific of how u use a filter right after security
filter to populate User bean and put it in Session?
example:
public class LoginFilter implements Filter {
public static final String USER_BEAN_KEY = "USER_BEAN_KEY";
private FilterConfig filterConfig;
public void init(FilterConfig config) throws ServletException {
this.filterConfig = config;
}
public void destroy() {
}
public void doFilter(ServletRequest req, ServletResponse res,
FilterChain chain)
throws IOException, ServletException {
HttpServletRequest request = (HttpServletRequest)req;
HttpSession session = request.getSession();
if (null == session.getAttribute(USER_BEAN_KEY)
&& null != request.getUserPrincipal()) {
session.setAttribute(USER_BEAN_KEY, request.getUserPrincipal());
// do your post authentication stuff here
Principal principal = request.getUserPrincipal();
...
}
chain.doFilter(req, res);
}
}
and in the web.xml:
Security Filter
/*
LoginFilter
I am thinking of somehow constructing User bean in subclass
of SimpleSecurityRealmBase, then if authentication pass,
store this bean somehow and pass it along to requested Action
specified in struts-config.xml.
Another idea is to somehow integrate SimpleSecurityRealmBase
into an Action class...
Thanks
In the struts config you can add a role="admin" parameter. It means
struts will check that the user has that role before it allows the
action to be executed. Can't remember what happens if they are not
authenticated - might throw an exception that you can catch and display
an error message?

Re: SecurityFilter Question?
I guess it depends on what sort of application you have. Normally, you might display a welcome page and give access to all the stuff that doesn't need a user to login. If everything requires them to be authenticated, you could just display the welcome + the login form. Once they log in, display some sort of welcome page for that user. This might have the menu of links they can use. If you use tiles you can insert a tile for a user or admin based on role eg Or use the struts logic tag which would allow only roles user and guest. Another way is just to display the link to an action in /user/*, if they click on the link and they are not authenticated or have the role of 'user' they will be directed to the login form. Once they login and they have the role of 'user' then they will get to the /user/* action they requested at the start. So you don't need to do any thing special in this case.

Re: Token is re-generated automatically.
I see.
You have a form for adding new users.
When you submit this form, it adds the user, then clears the fields and
redisplays the form ready for another user to be added. After saving
the record you create the new token so that the next user can be added.
When you detect that the form is submitted twice (eg from pressing the
back button) you display an error message on the form.
The problem comes with handling this error condition. One way would be
to clear the form fields when this occurs.
if (!isTokenValid(request)) {
errors.add(ActionErrors.GLOBAL_ERROR,
new ActionError("error.transaction.token"));
saveErrors(request, errors);
addUserProfileForm.reset(mapping, request)
return mapping.findForward("failure");
}
In this case, when the invalid token is sent you will return them to the
form, display the error messages but this time the form fields will be
empty/reset. A new token would have already been created and the user
will have to re-enter the form fields.
I normally don't call the reset() method on forms. I create a method
called clear() in the form bean which I use for clearing fields. On
these admin pages where you might add a lot of records it can be nice to
leave some fields with the last value entered as the records sometimes
are closely related. Obviously clearing the main identifiers like
username, password etc but fields like city or country might not change
very often.
PC Leung wrote:
token is saved if checking is OK.
saveMessages (request, actionMessages);
saveToken(request);
addUserProfileForm.reset(mapping, request);
return mapping.findForward("success");
I add saveToken() right after resetToken() in order to do testing.
The result is the same.
As you describe in step 5, a new token is generated.
So the token becomes eventually.
Actually, it is a another duplicated submission.

It sounds like the following is happening:
1. server generates page with token A, page with token A submitted
2. token A is valid, record saved, tokenReset() called, saveToken()
called creating token B
3. user presses back button, and resubmits old form with old token A
4. old token A does not match token B in session, user redirected to
"failure"
5. server generates new page with token in session (token B)
6. user submits page with token B, which is accepted with new token B
stored in session
Perhaps you could post more of your action where you have anything that
uses/resets tokens?

Re: Tiles - proper way for choosing a tile dynamically
If you are using container managed security or the security filter you could use
request.isUserInRole("admin") checking in the action. But Tiles also supports
request.isUserInRole checking in the definition and tags eg
You could probably try using this in your definition
then on the page you would just use
and see if the second menu overrides the first as they have the same name (I assume it
does).
It also works on the tiles:insert tag too, so you could use this on the page in
question
David Friedman wrote:
Janne,
You could set everything dynamically in the tile using something like this
(don't quote me if you like it, just look it up!):
public class TestAction extends TilesAction {
public ActionForward execute(ComponentContext context,
ActionMapping mapping, ActionForm form, HttpServletRequest
request,
HttpServletResponse response) throws Exception {
if (request.isUserInRole("admin")) {
context.putAttribute("menu", new String("menu-admin.jsp"));
} else {
context.putAttribute("menu", new String("menu-user.jsp"));
}
return super.execute(mapping, form, request, response);
}
}
Then, you don't need the unstandard:bind or EL tags, just the tiles:insert
tags.

Subject: Tiles - proper way for choosing a tile dynamically
I use Tiles to create pages that have their tiles selected dynamically based
on some information that is created in an action. One simple example could
be a menu tile, which is selected based on an attribute that is stored in
session. I created simple definitions like:
...
then, in menu.jsp page I include either "admin" menu or "user" menu based on
the session parameter:
Now the question: is this the "proper" way to do this, or is there a more
elegant method?
PS. if those tags confuse, they use jakarta unstandard
taglib to enable JSTL to compare the object in session to typesafe
enumeration values. In scriptlets this would be written simply as
<% if (cd.business.Role.ADMIN.equals(session.getAttribute("role")) { %>

Re: Interesting tiles/redirect interaction problem
From what I can see here it looks like the page is already being written out when the error occurs from what I can see. You have gone to your first action, done some work, then return the mainLayout tile. The tile then starts building the response based on layout2.jsp. It includes the pages you have in the list. showBorrowerDemographics.do?detail=summary is calling an action and the result is included in the page. When the error occurs, it redirects to the applicationFailure tile, and it is included in the mainLayout. Perhaps you either need to change your applicationFailure tile so it returns a tile page instead of a complete web page. Or have showPaymentHistory throw a different exception which gets caught and returns a tile. If your main action failed it would want to throw the exception and have a whole page constructed and returned, but a tile should return a simple tile not a whole page. Jim Barrows wrote: I'm using tiles, and some of the tiles are summary pages. For instance a payment summary, it just shows the date and the amount. While the detail page shows how the payment was applied (how much to interest etc.) So my tiles definition looks like: Okay, this works... now let's say /showPaymentHistory.do encounters something catastrophic, like DB down etc. So, it throws a BusinessObjectException. Cool.. that works Now, I've never used the exception handling stuff in struts-config.xml so here's the definition: And the handler says: LogWrapper.logAlert( "Business Object Exception: " + ex.getMessage()); ActionForward forward = mapping.findForward( "applicationFailure"); return forward; and the forward has redirect = true in the struts-config.xml So. I would expect that even though the summary pagelet is throwing the exception, that it would forward to the applicationFailure tiles definition. What I didn't expect was for the entire page to end up nested inside the original page being requested. Shouldn't redirect=true do what I expect with regards to tiles? and pop to a new tiles definition rather then include it? - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] -- Jason Lea - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: ApplicationProperties_es_ES
The resource bundles try to match the most specific bundle it can find eg is language and country are provided it will use that. If only language then it will try that. So the order for a locale of 'es_ES' will look for files in this order 1. ApplicationProperties_es_ES.properties 2. ApplicationProperties_es.properties 3. ApplicationProperties.properties So if you have a locale of 'es' then it will try 1. ApplicationProperties_es.properties 2. ApplicationProperties.properties If a key is missing in the most specific property, it will check the next one in the list. English example: ApplicationProperties.properties: home.greeting=Greetings ApplicationProperties.properties: home.farewell=Farewell ApplicationProperties_en.properties: home.greeting=Hello ApplicationProperties_en.properties: home.farewell=Goodbye ApplicationProperties_en_US.properties: home.greeting=Howdy ApplicationProperties_en_AU.properties: home.greeting=G'day Mate ApplicationProperties_en_NZ.properties: home.farewell=See ya So someone from en_NZ would see 'Hello' as it would use the home.greeting key from ApplicationProperties_en.properties. So someone from en_NZ would see 'See ya' as it would use the home.farewell key from ApplicationProperties_en_NZ.properties. You could put 90% of the en language into the _en file, and just put keys where things like spelling change in the country specific parts.

Re: philosophical question/poll about Struts/JSTL, scriptlets
Tomcat 5 includes *"JSP Custom Tag Pooling* - The java objects
instantiated for JSP Custom Tags can now be pooled and reused. This
significantly boosts the performance of JSP pages which use custom tags."
I seem to remember reading somewhere (can't remember where, does someone
have a link) that JSPs that don't have scriptlets can have the taglib
pooled. I assume this means the taglib is loaded and shared amongst
each JSP that uses them, speeding up the page and reducing memory. I
guess a scriplet on a page may make the web server make a local copy?
I find with Tomcat 5+JSP 2.0 that writing pages with tags and EL has
made them much easier to write and understand. With being able to get
rid of tags and just use ${var} everywhere makes them much
easier to read.

I also changed to tomcat 5.0 + JSP 2.0. You can stop using the struts-el tags and just use the normal struts tags. Erez Efrati wrote: Hi, I am working with Struts 1.1 + JST 1.0 tags.

Re: internationalization problem
(I haven't tested the following, but I have heard that it works)
I believe the problem is that a different system is used for reading form fields when
a file upload is used. The current Struts system doesn't use the encoding supplied,
so it assumes the default Latin-1 encoding. I believe there is a patch that will use
encoding supplied by the browser (not sure if this works as some browsers may not send
the encoding in some circumstances).
I think there is a work around though. Struts uses Commons Upload to handle the file
uploads through it's own MultiPartRequestHandler. If you replace this with your own
one you can set the encoding as follows:
Struts will use org.apache.struts.upload.CommonsMultipartRequestHandler by default to
handle extracting the parameters out of the request and populating the form. It uses
the DiskFileUpload class from Commons FileUpload. It is that handler that we need to
modify, to do that we could create our own using the
org.apache.struts.upload.CommonsMultipartRequestHandler source as the basis. You will
need to download the source to see how it works.
We need to tell Struts to use ours instead of the defualt by adding this to your
struts-config.xml
Then to modify org.apache.struts.upload.CommonsMultipartRequestHandler by creating our
my.own.MultiPartClassHandler class.
We need to modify the handleRequest() method like so:
// Create and configure a DiskFileUpload instance.
DiskFileUpload upload = new DiskFileUpload();
upload.setHeaderEncoding("UTF-8");
// Set the maximum size before a FileUploadException will be thrown.
upload.setSizeMax((int) getSizeMax(ac));
...
Then struts would read the form fields using UTF-8 instead of the default Latin-1
encoding.

Subject: internationalization problem
Hi,
I am facing a problem and trying to solve it for
many
days but in vain.
The user selects the locale(suppose es-spanish)
and
the page displays in that particular locale using
the
appropriate properties file.
I also have a file upload on the same form. I am
using
enctype="multipart/form-data" in the
tag.
Now when I enter Arabic text in the text field,
and
post the form, the Arabic text is not retained. It
inserts junk characters.
Can anyone please help me on this issue.

The SimpleDateFormat has a setTimeZone() method (coming from
DateFormat).
The locale doesn't have timezone information, locale is about language
and countries. Countries may have several different timezones so there
is no accurate way to map them to timezones. I normally allow users to
pick their own timezone and store that in some preference settings for
them. Then display date/time using that timezone.

Re: System.out.println
Log4j has configureAndWatch which looks for changes to the configuration file. As for commons-logging it doesn't have it yet: http://www.mail-archive.com/[EMAIL PROTECTED]/msg10152.html So the other suggestion of having an action to reload or change the level is probably your best bet right now.

Re: Encoding of ApplicationResources file
Hi,
You need to use native2ascii (program comes with java sdk and is also an
ant method) to convert the UTF-8 (or other formats) into the java
property file format which use \u
I normally refer people here also for some other tips:
http://www.anassina.com/struts/i18n/i18n.html
But it doesn't seem to be working for me :(
Main point is you need to request.setEncoding("UTF-8") on every request
(well, ones that have form values being submitted). Otherwise they will
be treated as normal ascii and be corrupted. Also pages need the
response encoding or page encoding set to UTF-8 too.

Re: struts response character encoding.
Olve SÃther Hansen wrote: Now I am saying false things. I thought my baseLayout.jsp had this entry.. It didn't. So it is enough specifying <%@ page contentType="text/html; charset=UTF-8"%> in the base tiles file if that architecture is used. I think it that should work. But I think I ran into a problem when pre-compiling the JSP pages when using the 2.3 spec. If you don't pre-compile I think it should be ok. If you do pre-compile, each JSP is passed to the compiler and the compiler does not know the encoding, so it uses the default. This is why I ended up adding it to all pages. -- Jason Lea - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: struts response character encoding.
iso-8859-1 is the default page encoding for web pages. To use anything else you need
to tell the webserver.
Use this at the top of every jsp page:
<%@ page contentType="text/html; charset=UTF-8"%>
Or for Tomcat 5 you can use Servelt 2.4/JSP2.0 spec and set the page
encoding in the web.xml
*.jsp
UTF-8

I have some problems using struts/tiles and UTF-8 characters embedded in

How can I make struts/tiles respect the system default encoding, and not

This problem occurs in tomcat 4.1.29, 5.0.19 and 5.0.27.
I have a struts version bundled with Appfuse, all I know is that it is
from 2003-12.02 (that is 2. december).
It seems like struts is hard-coding the response encoding to be
ISO-8859-1, although the response-encoding is set to be UTF-8 for all
requests..
In a struts-action I execute this code:
log.debug("res encoding: " +response.getCharacterEncoding());
log.debug("req encoding: " +request.getCharacterEncoding());
resulting in:
res encoding: ISO-8859-1
req encoding: UTF-8
I use the SpringFramework characterEncodingFilter to force utf-8.
My web-browser reports the page to be encoded in utf-8.
If I use iconv (a Linux program for converting files from one encoding
to another) to convert a file containing utf-8 characters (norwegian
characters à à Ã) to iso-8859-1, the pages displays correctly.
My web-browser still reports the page as being encoded in utf-8.
If I write the same Norwegian letters in a jsp page outside of
struts/tiles control, the page displays without problems..
So, is there a way to make struts/tiles respect the system default
encoding, and not use iso-8859-1 for all jsp pages?
Hope someone can help me solve this problem, I have looked through most
email archives I can find without any solution.
